This research explores the utilization of the Rössler chaotic attractor in designing a broadband electromagnetic absorber with superior performance across the 2–20-GHz frequency range. The study commences with an in-depth exploration of the parameters governing the Rössler chaotic system, culminating in the generation of intricate three-dimensional spatial representations. Given the standardized thickness of 0.035 mm for the z-axis in the absorber structure, these three-dimensional models were carefully processed through iterative algorithms using Julia Fractal transformations. This process facilitated the derivation of two-dimensional chaotic patterns, which were subsequently subjected to rigorous simulations to evaluate their electromagnetic absorption properties. In the proposed absorber design, the chaotic patterns were developed using a resistive ink with an accurate thickness of 0.035 mm, integrated with an FR-4 substrate. To maximize absorption efficiency, the absorber backplane was coated with copper at a standardized thickness of 0.035 mm. A comprehensive parametric analysis was conducted to examine the influence of critical design factors, including substrate thickness, absorber dimensions, and polarization modes across varying incident angles, on the absorption characteristics. The findings emphasize the unique capabilities of the Rössler chaotic patterned absorber, unveiling its exceptional potential for deployment in a range of contemporary applications. Significantly, this study signifies a pioneering endeavor in applying the Rössler chaotic methodology to the design and optimization of metamaterial absorbers. This contribution not only strengthens the theoretical understanding of chaotic systems in electromagnetic applications but also establishes a novel framework for future advancements in the field.
